' GEORGE SHOEMAKER, OF PHILADELPHIA, PENNSYLVANIA, AS SIGNOR To WILLIAM WHARTON, JR, acOMPANY, INCORPORATED. OF PHILA 'DELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

1'0 aZZ' whom it may concern/r Be itknown that I, GEORGE SHOEMAKER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Railway-Track Structures,

of which the following is a specification.

' My invention relates to certain improve= ments in railway-track structures, such as;

' frogs, switches, crossings, and drawbridgeline 4 4, Fig. 3. Fig. 5 is a perspective view funnels, where it is desired to attachone or more rails to a casting. I

The object of my invention is to provide means whereby the rail or rails can be permanently attached to the casting and the base of the casting been a .plane with the base of of a portion of the structure; and Fig. 6 is a plan View of a;switclimate', illustrating my invention. g A isthe body of the frog structure, consisting of a casting having intersecting wheelflange grooves and tread and guard portions,

which are inline with therails. At each end of the structure shown in Fig.1 are three projecting arms a a a (Olearly shown in Fig. 5.) These arms are spaced a'sufficient distance apart to allow for the insertion of the ends of the rails B B and GO and the securing metal e. The inner walls of the arms follow the: general contour 01 the rails, but do not extend above or below the rails, so that the base of the structure is on the same plane as the bases of the rails.

In order to secure the rails rigidly'to the structure, I preferably perforate the rails atb and c and form cavities e in the walls of the structure, as shown in Figs. 3 and 4, and these cavities are preferably undercut, as shown.

' To assemble the parts, the ends of the rails are mounted in the space between the'arms and heldin proper alinement. while molten metal e, suchas zinc,is poured into the s ace between the. rails and the inner walls 0 the arms, the metal flowing into the cavities and Specification of Letters Patent.

through the holes in the rails, and when the metal is set the rails will befirmly secured to the structure.

In Fig. 6 I have shown a switch-mate A having three arms a at one end and twoarms a at the opposite end, so that two rails B and G can be attached to one end of the structure and a single rail B can be attached to the opposite end.

structure or to a track structure to which a bridge-funnel. p I In an application for patent filed byArthur B. Davenport, J r., on the, 28th day of Febru ary, 1905, Serial N 0. 247,688, the idea of securing the rails in pockets in the structure is broadly claimed, and I therefore lay no claim to this feature in this application.

' I claim as my invention 1. A railway-track structure having two arms at one end, said arms beingspaced apart to receive a rail and the securing metal, the.

space being open at top and bottom, substantially as described.

2;.A.railway,- track structure having two arms at one end said arms bein spaced apart to receive a rail and the securlng metal; the space being open at top and bottom, the inner walls of the arms having" cavities therein for the securing metal, substantially as described.

3. .The combinationof a railwaytrack,

structure having two arms :at' one end, 'a rail mounted in the space between the arms and securing metal filling the space between the inner walls of the arms and the rail, the base of the structure and the base of the rail being on the same plane, substantiallyas described.

, 4. The combination of a railway track structure havingtwo arms at oneend, a rail mounted in the space between ,the arms and securing metal filling the spacebetween the inner walls of the arms and the rail, the base of the structure and the base of the rail being on the same plane, the inner walls of the arms having cavities therein and the end portions of the rails being perforated, substantially as described.

5. The combination of a railway track structure such as a frog, having three arms The invention .can be applied to a crossing projecting from each end with a rail mounted name to this specification in the presenee of in each sfim'ce formfisd by the arms, mulll seou11- two subscribing Witnesses. ing mete filling t e space between t e mi s and the arms, the spaces between the arms GEORGE SHOEMAKER' 5 being open at top and bottom, substantially Witnesses:
